mwandelaar Hmmm, a little bit of a late reply. The logfile clearly stated openvpn_as is started so it's installed anyway. Maybe not via a package-manager but via an other way like extracting a archive-file or restoring a directory from a backup. The openvpn_as is started via the init-proces so somewhere in /etc/init.d AND /etc/rc3.d are files pointing to openvpn_as. Try to move them away from this place (be sure you can put it back if something gets broken!) and restart. See if you can start a normal openvpn server.
teckins Its alright, Im late myself. What files should I remove ? There are a bunch of files in the directory.
mwandelaar Check if you have any files with names like "opevpn_as" of with "access-server" in it. When in doubt, just do an: ls -l and post the output here. (There's no identifiable info about your serrver there, so don't be afraid to post)
